For the transversity GPDs \(H_T\)  and \(\bar{E}_T\)  the parameterization (REF ), (REF ) is
also employed and the parameters, \(B_i^a\)  and \(\alpha ^{\prime }_i{}^{a}\) , fixed from the low \(-t\)  data on
deeply-virtual pion electroproduction [1]}, [2]}. The values of these parameters can be found in [3]}.
For wide-angle photo- and electroproduction the large \(-t\)  behavior, i.e. the second term in the profile function,
is also required. As in [3]} we use for the relevant parameter \(A_i^a\)  the value \(0.5\,\,{\rm GeV}^2\)  for all
transversity GPDs. With this choice a good fit to the CLAS data [5]} on \(\pi ^0\)  photoproduction has been
obtained.
At present there is no information available on the GPD \({\widetilde{H}}_T\)  and its associated from
factor \(S_S\) . In order to have an at least rough estimate of its importance we assume, with regard to the
definition of the GPD \(\bar{E}_T\)
\(\bar{E}_T\,=\,2\widetilde{H}_T + E_T\,,\)
